Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523674, here are decompositions:

5 + 31523669 = 31523674
23 + 31523651 = 31523674
41 + 31523633 = 31523674
137 + 31523537 = 31523674
197 + 31523477 = 31523674
233 + 31523441 = 31523674
263 + 31523411 = 31523674
293 + 31523381 = 31523674

Showing the first eight; more decompositions exist.
